Lots of ways to measure the effectiveness of ownership
win/loss
franchise health
infrastructure/facilities
community engagement
culture
league influence and leadership
Probably many more...In many ways the Wilfs have been exemplary, shining beacons of pro sports ownership, not just nfl ownership.
They've also had the benefit of a financial balance sheet previous owners here could only dream about with USB generating cash and franchise growth value.
Some will look at only the win/loss record.
Lots of ways to tell the story of the Wilfs and The Vikings. IMO they have been exemplary, in spite of fleecing me for PSL $$.
